Nasdaq Market Data Vendors

As a service to users, the Nasdaq Trader website provides links to real-time market data vendors. To help facilitate the selection of a real-time data provider, the vendors have indicated which of the following service levels are supported on their products:

Entitlement Description of Data Access
TotalView Nasdaq TotalView — the standard Nasdaq data feed for serious traders — displays the full order book depth for Nasdaq market participants. TotalView also disseminates the Net Order Imbalance Indicator (NOII) for the Nasdaq Opening and Closing Crosses and Nasdaq IPO/Halt Cross. For more information on TotalView, please refer to the Nasdaq TotalView page.
Level 2 Level 2 provides the top-of-file position for Nasdaq exchange participants. In 2007, Nasdaq expanded the Level 2 product to include market participant depth in NYSE- and other U.S. regional exchange-listed securities.

Due to the high level of customer inquiries, vendors were asked to indicate if they offered a data feed or Internet-based product. Please contact the vendor directly for product pricing and ordering information.
